I bought the whitening pre-brush mouthwash.This product was not what is was cracked up to be. It burnt  every second I had it in my mouth, and it didnt make a difference. I bought one of those big bottles, and used the whole bottle thinking it would be worth it when i was finished. I was wrong. My teeth are still the same color and I didn't feel any more refreshed. i would not recommend this product to any one. I was really excited when I bought this from the store and I ended up just being dissapointed. I dont even want to try any of their other products.
